Experimental determination of deflagration explosion characteristics of methan-air mixture and their verification by advanced numerical simulation

Popis výsledku v původním jazyce

Venting is a widely applied method to protect buildings and technological equipments from effects of internal explosion. The key problem in venting is the adequate design of vent area and an effective material of venting element. ? set of 76 experimentson partly confined methane-air mixture explosions with various parameters was processed. In terms of experiments, vent areas and venting elements with variable values of static activation pressure were changed. During measurements, certain items were determined at steady stoichiometric mixture concentration and atmospheric conditions: reduced explosion pressures, rates of reduced explosion pressures rise, temperatures, flame lengths and deformations of experimental equipment enclosure. Together with experiments, modelling of these processes was carried out by the codes based on computer fluid dynamic (CFD) using numerical tool FLACS (Flame Acceleration Simulator). Results of experiments and CFD models are analysed and compared to each o
